/**
* nsICookieService
*
* Provides methods for setting and getting cookies in the context of a
* page load. See nsICookieManager for methods to manipulate the cookie
* database directly. This separation of interface is mainly historical.
*
* This service broadcasts the notifications detailed below when the cookie
* list is changed, or a cookie is rejected.
*
* NOTE: observers of these notifications *must* not attempt to change profile
* or switch into or out of private browsing mode from within the
* observer. Doing so will cause undefined behavior. Mutating the cookie
* list (e.g. by calling methods on nsICookieService and friends) is
* allowed, but beware that there may be pending notifications you haven't
* seen yet -- for instance, a "batch-deleted" notification will likely be
* immediately followed by "added". You may check the state of the cookie
* list to determine if this is the case.
*
* topic : "cookie-changed"
* broadcast whenever the cookie list changes in some way. see
* explanation of data strings below.
* subject: see below.
* data : "deleted"
* a cookie was deleted. the subject is an nsICookie2 representing
* the deleted cookie.
* "added"
* a cookie was added. the subject is an nsICookie2 representing
* the added cookie.
* "changed"
* a cookie was changed. the subject is an nsICookie2 representing
* the new cookie. (note that host, path, and name are invariant
* for a given cookie; other parameters may change.)
* "batch-deleted"
* a set of cookies was purged (typically, because they have either
* expired or because the cookie list has grown too large). The subject
* is an nsIArray of nsICookie2's representing the deleted cookies.
* Note that the array could contain a single cookie.
* "cleared"
* the entire cookie list was cleared. the subject is null.
* "reload"
* the entire cookie list should be reloaded. the subject is null.
*
* topic : "cookie-rejected"
* broadcast whenever a cookie was rejected from being set as a
* result of user prefs.
* subject: an nsIURI interface pointer representing the URI that attempted
* to set the cookie.
* data : none.
